Frequently Asked Questions
Why does the RGI-750 have two manways?
The RGI-750 is a two-compartment interceptor. The inlet chamber captures the bulk of grease and solids; the second chamber provides additional clarification before discharge. Each compartment has its own 6" manway so maintenance crews can inspect and service each chamber independently without disturbing the entire unit.
What is the greasy sludge capacity of the RGI-750?
The RGI-750 holds 3,780 lb of greasy sludge across its 750-gallon two-compartment liquid volume — designed for extended service intervals in very high-volume commercial food service operations.
Can the RGI-750 handle heavy truck traffic?
Yes. The 3/8" nonskid diamond treadplate cover is H20 load rated — rated for commercial and highway truck traffic. The unit can be installed flush with grade in parking lots, loading areas, and service drives where vehicles cross the cover.
Is the RGI-750 returnable?
No. The RGI-750 is custom-built to order and non-returnable. Confirm capacity, manway height, pipe sizes, and local plumbing code requirements with your engineer or plumbing inspector before ordering.
Can the manway height be customized?
Yes. The standard RGI-750 ships with 6" tall manways. If the unit will be buried deeper or installed under a paved overlay, specify the required manway height at time of order. Both manways can be set to the same custom height.
What construction standard does the RGI-750 meet?
The RGI-750 is built to IAPMO/ANSI Z1001-2014 — the nationally recognized construction standard for fabricated gravity grease interceptors, referenced by commercial plumbing codes across the United States.
